As an entertainment-oriented cartoon, some logical irrationality can be completely ignored. For example, the same voice, similar appearance, similar living habits, etc., are also to make it easier for the audience to accept. It also saves time on key plots.
The animated expressions and language are very humorous. As a pure entertainment movie, it should be pretty good.
As for the theme of the exploration of the unknown, different people have different opinions. Why always imagine the arrival of aliens as aggression rather than communication, hostility rather than friendliness, the source is the evil mirror image of mankind towards itself.
The unknown can make people scared and yearn for.
The key depends on how you face it.
